MACHINE FOR SETTING SPECIFICATION forming part of Letters Patent No. 561 ,324, dated June 2, 1896.

Application filed March 7, 1896- To all whom it may concern:

Be it known that I, ELEAZER KEMPSHALL, of Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Setting Metallic Fastenings, of which the following is a specification.

This invention relates to machines for setting button-fasteners and other like devices; and it has for its object to provide means for accurately feeding or supplying the fastening devices, one at a time, to the driver, which inserts and sets them.

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of a machine embodying my invention. Fig. 2 represents a side view, and Fig. 3 a sectional view, of portions of the machine, the driver being raised. Figs. 4 and 5 represent views similar to Figs. 2 and 3, the driver being depressed. Fig. 6 represents a section on line 6 6 of Fig. 2, looking toward the left. Fig. 7 represents a section on line 7 7 of Fig. .2. Fig. 8 represents a section on line 8 8 of Fig. 4. Fig. 9 represents a section on line 9 9 of Fig. '7. Fig. 10 represents a section on line 1O 10 of Fig. 6. Fig. 11 represents a View similar to Fig. 10, showing the fingers in a different position. Fig. 12 represents a side view of the holder. Fig. 13 represents a sectional view of a modification. Fig. let represents a section on line 14. 14 of Fig. 13. Y

The same letters and numerals of reference indicate the same parts in all the figures.

In the drawings, a represents a supportingstandard, having an overhanging arm a and a lower arm a".

i) represents the driver-bar, which is reciprocated in a vertical guide in the arm a by means such as a pivoted lever 79 a rod 11 connected with the lever 11 a spring 1), arranged to press the rod b downwardly, anda treadlelever b adapted to be moved by the operators foot to force the rod Z2 upwardly.

0 represents a holder adapted to receive a fastening device, such as a two-pronged button-fastener d, and hold the same in the path of the driver Z). Said holder comprises Serial No. 582,302. (No model.)

a tube 2, which receives the lower part of the driver, and spring-jaws 3 in said tube form ed to yieldingly support a fastener, as shown in Fig. 7. The holder is provided with spring-catches 5 5, which engage notches in the driver and yieldingly connect the holder therewith, so that the holder moves up and down with the driver during portions of its movement, the holder moving downwardly with the driveruntil it strikes the article (1, into which the fastener is to be inserted, and then remains stationary while the driver completes its downward movement, as shown in Fig. 8, and until the upward movement again brings the 'notches 'of the driver into engagement with the catches 5 5, whereupon the holder is raised with the driver, as shown in Fig. 7.

6 represents a fastener-reservoir, and e a chute extending downwardly therefrom to conduct a column of fasteners toward the holder 0. When the driver and the holder 0 are raised, as shown in Figs. 1, 2, and 3 the lower end of the chute coincides with an opening 6 in one side of the tube 0, said opening being formed to receive a fastener d and permit it to enter the space between the jaws 3 8.

The machine is provided with alet-off mech- 8o anism actuated by the movements of the driver-bar and by a sprin g ficooperating there with, to separate the lowest fastener from the column and permit it to enter the holder after each ascent of the driver-bar. Said mechanism comprises two fingers f f mounted 011 a carrier f which is movable crosswise of the chute, the said fingers pointing in opposite directions and being located at different heights, so that the finger f acts on the heads and the finger f on the prongs of the fastener, as hereinafter described. The said carrier is moved in the direction indicated by the arrow to project the finger .f between the heads of two fasteners, as shown in Fig. 10, by 5 means of a stud or projection f on the driverbar and a lever f pivoted at f to an car on the supporting-frame, said lever having a spring extension f against which the stud f 4 bears when the driver-bar reaches its highest 10o position. The lower end of the lever f bears on the carrier f and is moved inwardly toward the chute by the contact of the stud f with the extension f thus projecting the finj is to be engaged by the bent prongs of the ranged to cooperate with a projection on the ger f, retracting the finger f and compressing the spring f. The lowest fastening is thus detached from the column by the finger f and allowed to enter the holder 0, the column being held back by the said finger. the driver-bar descends, the stud f releases the lever f whereupon the spring f forces the carrier f away from the chute, thereby projecting the finger f and retracting the finger f, as shown in Fig. 11. is thus caused to support the column of fasteners, said finger being beveled, so that it permits the column to move forward far enough to bring the lowest fastener into position to be engaged by the finger f when the latter is again projected. It will be seen, therefore, that after each ascent of the driver the lowest fastener in the chute is separated from the column and driven into the holder a, partly by gravitation and partly by the impetus given bythe quick forward movement of the beveled end of the finger f against the head of the fastener.

The article cl, which may be supposed to be a garment, is supported by a yielding dieblock 1' in the arm a is formed to clench or turn the prongs of the fasteners, is here shown as provided with a cavity to receive a button j, whose cross-bar 3 fastener, as shown in Fig. 5.

My improvements may be used in machines for setting rivets, lacing-hooks, and other de- 1 vices, and are not limited to use in connection 1 with button-fasteners.

It will be seen by reference to Fig. 6 that the finger ff moves on one of the fastener head-supporting surfaces of the chute and 1 acts directly on the heads of the fasteners, so that it forces the fasteners forward without tending to tip them, as it would if arranged to bear on the prongs below the head. The 1 yielding extension 7" of the lever f enables the finger f to yield in case it does not prop- WVhen The finger f I Said die-block, which erly encounter a fastener-head, thus preventing liability of breakage.

In Figs. 13 and 14 I show a modification of the means for yieldingly supporting a fastener in the holder, said modification being a bifurcated jaw 6, mounted on the free end of a spring 7, the arms of the jaw being formed to project under the head of the fastener.

I claim- 1. In a machine for setting metallic fastenings, the combination of a chute, a driver movable across the chute, a holder embracing and movable with the driver and having means for detachable engagement therewith whereby the holder is raised by the driver to position to receive fastenings from the chute, fastener-supporting jaws in the holder, and means actuated by the driver for discharging fastenings singly from the chute into the holder when the latter is elevated.

2. In a machine for setting metallic fastenings, the combination of a chute, a driver movable across the chute, a holder which coincides with the chute when the driver is raised, a cut-off movable crosswise of the chute and comprising a carrier, two oppositely-projecting fingers arranged to act alternately on a column of fasteners in the chute, a lever pivoted to the supporting-frame and having at one end a yielding extension ardriver, its other end being arranged to impart motion in one direction to the carrier, and a spring which presses the carrier in the oppo- 1 site direction.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 15th day of February, A. D. 1896.
